Veil of Obscurity

This wondrous architecture disguises up to twenty contiguous stronghold spaces (or two levels of ten contiguous stronghold spaces each) with a mirage arcana effect, making the structure appear as something other than it is. It includes audible, visual, tactile, and olfactory elements, though it can’t disguise, conceal, or add creatures.

Caster Level: 10th; Prerequisites: Craft Wondrous Item, mirage arcana; Market Price: 25,000 gp.
